# Factoring and Fractions

By M Bourne

Many mathematics formulas involve factorising. It makes your mathematical life a lot easier if you are confident when factoring complex expressions.

Even though we use decimals more than we use fractions in everyday life, an understanding of fractions is still important in mathematics, especially in algebra.

## Overview of This Chapter

We start with a reminder on how to expand expressions like (*x* + *y*)^{2} in the Special Products section.

Then we will learn how to:

- Factor expressions like
*a*^{2}−*b*^{2}in Difference of Squares, followed by... - Factoring Trinomials (e.g. 3
*a*^{2}+ 2*ab*−*b*^{2}) then - Factoring Cubes like
*a*^{3}−*b*^{3}.

The final part of this chapter is about **algebraic fractions**.
